Chris Brown has been living with Karrueche Tran - who he dumped for on/off ex-girlfriend Rihanna in October - with reports suggesting the pair have been getting close since his birthday earlier this month.
The 24-year-old rapper - who recently split from his on/off girlfriend Rihanna, who he is still on probation for beating in 2009 - had dumped the model for the 'Stay' hitmaker in October but it looks like they could be back together.
The pair have been spotted getting close in public recently - including at the Billboard Music Awards in Las Vegas - and now gossip site TMZ has reported they are living together.
A source has told how they ''hooked up'' earlier this month just before Chris' 24th birthday, and Karrueche has been staying at his home ever since.
Although it is said she has kept her own apartment, the site revealed she has moved most of her belongings to his Hollywood Hills house.
Rihanna is apparently heartbroken with news Chris is spending time with his ex-girlfriend.
An insider previously said: ''Pals have told Rihanna not to get upset about Chris and Karrueche. They think the best revenge would be living well and looking good, but so far Rihanna's answer has been to party the pain away.
''It's understandable that she'd want to escape her feelings on this but she's taking it way too far. Everyone around her wants her to get some help -- they're genuinely worried about her.
''She's not in a good place and looks like she's self-destructing. Her friends are really worried about her and think she needs to take time out to detox and refocus.''
